Topic 1:1. Chapter 7 covers drinking water distribution systems. Select a real city with at least 20,000 people (possibly whereyou live). Contact the water department, review their website, or do other investigations, and write a paper including,but not limited to, at least five of the following items:a. population served and locationb. water source (e.g., lake, aquifer, other)c. when the system was first constructed and dates of upgradesd. types of pipe materials in the systeme. initial cost of the systemf. design water flow rate for the systemg. approximate total length of pipe in the systemh. number of water towers and/or pumping stationsi. Indicate the vertical elevation change from the water treatment plant to the lowest and highest elevation homeor business served by the water system.j. largest pipe diameter in the systemk. problems with the system (e.g., recurring leaks, pipe deterioration, toxic chemical infiltration, chronic lowpressure)l. type of disinfection used and whether or not fluoridation is usedm. special attributes of which the city is especially proud

Topic 2:2. Chapter 8 covers sanitary sewer systems.
